Tamiya 15251 - 19mm aluminium roller with plastic ring, race-ready upgrade for Mini 4WD  [15251]

Compact 19mm roller Tamiya 15251 with plastic ring

The Tamiya 15251 offers a 19mm aluminium roller paired with a plastic outer ring, created to improve Mini 4WD handling and durability. Lightweight yet robust, it suits pilots who want reliable corner behaviour without heavy modification to their cars.

Materials and chassis fit

Crafted from sturdy aluminium for low weight and strength, the roller includes a plastic ring that reduces rubbing and dampens noise. The resulting smoother rotation helps cars negotiate bends on different track surfaces. It fits many common Tamiya Mini 4WD chassis such as MS and MA models with standard roller mounts.

Practical track use

These rollers are aimed at improving stability through curves, helping to keep lap times consistent and lowering the chance of crashes in tight sections. They are a sensible tune for anyone wanting better handling without replacing multiple components.
